Little owls on the move

The little owl, Athene noctua, is a small nocturnal owl and is classified as an endangered species on the German Red List. In recent years the existing population of little owls has successfully been stabilized in the south-west of Germany, and in some places numbers are even rising. In neighboring northern Switzerland on the other hand there is still no established population of little owls, even though habitat conditions seem suitable for the species. Now, a team of researchers headed by Severin Hauenstein from the Department of Biometry and Environmental Systems Analysis at the University of Freiburg has researched whether juvenile little owls from Germany could reach and re-colonize northern Switzerland. The scientists have published their results in the peer-reviewed journal Ecological Applications.
